The probability of the arrow stopping over Section-1 is 7/20
What is probability?
"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."
Formula of the probability of an event A is:
P(A) = n(A)/n(S), where n(A) is the number of favorable outcomes and n(S)
is the total number of events in the sample space.
For given example,
A spinner has three sections. The table shows the results of spinning the arrow on the spinner 80 times.
Section-1 Section-2 Section-3
28 36 16
We need to find the probability of the arrow stopping over Section 1.
Let event A: the arrow stopping over Section 1
n(A) = 28
For given example, total number of outcomes of sample space would be,
n(S) = 28 + 36 + 16
n(S) = 80
Using the formula of probability, the probability of the arrow stopping over Section 1 would be,
P(A) = n(A) / n(S)
P(A) = 28/80
P(A) = 7/20
Therefore, the probability of the arrow stopping over Section 1 is 7/20.
